This week, Facebook’s Trending Topics system was notably late to a huge social media protest, Elon Musk announced new solar roof panels that the company hopes will change how we consume electric power and Instagram tested shoppable tags. These are some of this week’s top stories in tech. Want to receive the Weekly Roundup in your inbox? Well, turns out you can.

1. Elon Musk unveiled Tesla’s new solar roof panels that the company hopes will revolutionize the way we use green power in the home. Also revealed was the new Powerwall 2.0 battery unit that now packs twice the energy storage. The solar roof tiles come in four distinct styles, and are transparent to solar but opaque when viewed from an angle. And they’re not just a fashion statement — the new tiles could become more efficient, durable and cost-effective than existing solar panel options.

4. A massive social media protest exploded on Facebook, yet Facebook’s Trending system was hours late in picking it up. People around the country were checking in on Facebook at the Standing Rock Native American Reservation in an effort to supposedly hinder local Morton County police from targeting protesters attending in person to fight an oil pipeline through historic tribal lands.

5. LinkedIn launched a new portal called Salary, which acts as a tracker to collect and analyze salaries globally. It will let users chart the connections between themselves, their career, their industry and the wider economy.

6. Google finally officially launched its Tango smartphone augmented reality system to the masses. Right now, it’s only available on Lenovo’s Phab2 Pro, which arrived in U.S. stores this week, but you can expect to see this in a bunch of Android phones in the next year or so.

7. Instagram wants to integrate a shopping experience into its app without interrupting your scrolling with a browser window. That’s why the social network is testing shoppable tags on photos. Retailers can tag products in their photos, which are hidden behind a “Tap to view products” button.
